Pronunciation: /ˈsɪŋklʌɪn/


A trough or fold of stratified rock in which the strata slope upwards from the axis. Compare with anticline.
Example sentences
  • A series of synclines and anticlines developed within the basin at several localities but most prominently south of the Aghios Georgios fault zone.
  • The faults have a systematic geometric relationship with folds, with anticlines in the mutual hanging walls of fault pairs and broader footwall synclines that define the shallow dish forms of the polygons.
  • A series of transverse anticlines and synclines are observed that have axes orientated NE-SW, approximately perpendicular to the fault zone.



Pronunciation: /sɪŋˈklʌɪn(ə)l/
Example sentences
  • It is distinguished from adjacent terranes of similar age by its open synclinal structure, obviously fossiliferous character, the thickness of essentially conformable strata, and the predominance of volcaniclastic rocks.
  • The tendency towards hydrostatic equilibrium would force magma updip beyond the synclinal axis, and cause the greatest thickness of magma to accumulate at the bottom of the sill.
  • Local unconformities and deposition in the foreland basin and intra-mountain synclinal basins occurred in discrete phases.


Late 19th century: from syn- 'together' + Greek klinein 'to lean', on the pattern of incline.
